The design of \(\mathsf {OFDM}\)  signals aims to simultaneously achieve high data rate, high spectral efficiency (measured by the adjacent channel power ratio - \(\mathsf {ACPR}\) ) and low computational complexity [1]}, [2]}, [3]}, [4]}. This design is highly affected by the nonlinear effects of the \(\mathsf {HPA}\) . While keeping the \(\mathsf {PAPR}\)  level low is favorable, there are other design criteria that should be taken into account. Specifically, it is of particular importance to have acceptable signal spectral behavior and \(\mathsf {BER}\) , which are often referred to as waveform design. These criteria often collide, and some trade-offs appear, thus lower \(\mathsf {PAPR}\)  levels are achieved with higher \(\mathsf {BER}\) .
